I've never heard of anything like that; permission on private property to do it I guess.
However, had an interesting deal last year. I got a call from a neighbor about a couple of professional snake hunters who were going to hunt his place and wanted to know about mine. I'm loaded with them but don't worry about them. I said OK and told him where the best places would be. About a week later he called and said they had backed out on the deal. I asked why and he said the limit for selling meat and skins had been reached for my region. I had no idea about limits.
Without a sense of urgency, nothing ever happens.
